SVST Sidewall planer

post #1 of 8
Thread Starter 
Hi,
I decided to spent the bucks and buy a planer, (SVST). Seemed simple enough, worked very well on my Rosis. Not so well on my Blizzards. No matter what angle I set the blade at, it chattered something awful on those skis. I ended up finishing off the job, (and removing the chatter marks), by hand with a panzar. This did not chatter at all.
Anybody know what I'm doing wrong? BTW, I'm not new to tuning.
Thanks

It is probably not the angle but the depth. Can yu adjust to take less material off. You need to make more passes and take just a tiny bit off on each pass.

 

this BY FAR is the best one I have found!!!!! Jon used to post here from time to time and I bought one from him!

A-man,
There is really no depth adjustment per se. The blade is the only point that touches the sidewall; there are no guide pins or wheels on the SVST. Do you think it could be the makeup of the plastic Blizzard uses? The sidewall itself is "wavy", kinda looks like a piece of wood that has saw marks.
Like I said, my Rosi peeled like butter.

    Race Blizzards, or all montains? Reason I ask is that the world cups have a "2nd metal edge" directly above the side edge. This can cause issues when first beginning to plane. 

 

    The depth setting Atomicman refers to involves those 2 little screws on top of the blade housing (I own this tool also, and I certainly agree with Amans endorsementicon14.gificon14.gificon14.gif) If you loosen these screws you'll find that you can move the blade either closer to the side edge or away from it. This is not for depth.  You can also rotate the metal cylinder which holds the blade. This is your depth setting. If you rotate it so the blade is perpendicular to the side edge, it will cut at it's maximum depth (DON"T DO THIS!!). If you rotate so its more parallel to the side edge, it is at its minimum and wont cut at all. Find the area in between these two extremes (maybe 30-40 degrees?, just a guess...), tighten, and begin with light, smooth passes at first, though you never want to bear down on it! This can take practice, maybe start on an older pair you don't care about too much. Stop when the blade is cuts up to the edge.

 

  Hope this helps

Hmmmmm. I understand what the blade angle is doing. This gets me to thinking, is it really the "barrel" that the blade mounts in that should ride on the side edge, allowing the blade to "peak below" that plane to control cut depth? It seems that with a single point of contact that just slight variations with the angle of the whole tool can cause the depth of cut to vary.
I do a lot of woodworking and have a feel for hand tools. This chatter is really weird, like I said, my Rosis planed well, no problems.
Thanks!

    Yes. It is this cylinder which rests on the side edge.  icon14.gif  If you use this in conjunction with what I wrote above then you're good to gowink.gif
